Keratoacanthoma Spontaneous regression.
Keratoacanthomas(KA) are rather common, rapid growing skin tumors, in which may occur as solitary lesions or in the form of multiple lesions.
Differentiation of KA from well-differentiated squamous cell carcinoma may be problematic .
Keratoacanthoma Spontaneous regression
KA is a rapidly growth on the skin that expands from 1-2mm to 1-3cm over a few weeks, and develops into a smooth dome-shaped growth with a central keratin core.
If untreated, KA's usually stop growing around 6-8 weeks, stay dormant and unchanging for 2-6 weeks, and then finally spontaneously regress slowly over 2 to 12 months frequently healing with scarring.
KA's are most commonly found in the hands, arms, trunk and face.
KA should be differentiated clinically and histologically from squamous cell carcinomas,
Treatment varies according to the type of lesions, but solitary lesions should be excised.
